I know, I have a ridiculous amount of journals. I started journaling late 2017 and at a rough estimate have completed about 100. This year I use on average an a5 journal a week.
That's only about 1/4 of them. I will use them all for journaling. I finish an a5 notebook in around 7 days so finish them really quick. I don't make junk journals. I should try and make some as they look like a lot of fun to use.
